CT-2 / CT-3
The "Channel Tag"
The Trilithic CT-2 or CT-3 Channel Tag is a headend-mounted device used with Trilithic's leakage receivers used to help identify leakage sources in overbuilt areas, to increase detection range and to increase immunity to interference. When several CATV systems operate in the same area, it is often difficult to determine which system is the source of a detected leak. The CT-2 and CT-3 solve this problem by "tagging" the system video carrier, or the carrier provided by the CT-3, with low-frequency modulation. This modulation is ignored by TV sets, but causes a distinctive response in Trilithic Searcher Plus and Super Plus leakage receivers, and the Tricorder signal level meters when operated in leakage mode. Used as a system with the Super Plus leakage receiver, the CT-2 and CT-3 channel tag eliminates all "false alarm" triggers and increases leak detection sensitivity by four times over previous models.
